On last night's episode, Oliver and Slade went on a rescue mission, attempting to save the mercenary's son, Joe, from a life sentence in prison. Well, they found Joe, who escaped incarceration thanks to the help of a new (and evil) mysterious group he's leading, called "The Jackels."

In the promo, Oliver and Slade discover just how dangerous Joe is -- and we're left to wonder whether he'll be able to bring Slade back to the dark side with his Jackels, or if he'll side with Oliver.

Take a look at the "Promises Kept" promo below.
